Europas Röntgenobservatorium XMM.
DOI: 10.1002/phbl.20000560210 Bibcode: 2000PhyBl..56...37S

Schartel, N.; Dahlem, M.

In den letzten 25 Jahren haben sich Beobachtungen im Röntgenlicht, neben optischen und Radiobeobachtungen, zum dritten wichtigen Standbein der Astronomie entwickelt. Die Dynamik dieser Entwicklung zeigt sich darin, dass den Astronomen seit dem Start von ROSAT immer wenigstens zwei Röntgensatelliten zur selben Zeit zur Verfügung standen. Im nächste…

The Temperature of the Hot DB GD 190
DOI: 10.1515/astro-2000-0110 Bibcode: 2000BaltA...9...43P

Provencal, J. L.; Shipman, H. L.

We are currently in the midst of an investigation of hydrogen and carbon abundances in hot DB white dwarfs. Our HST UV spectra give evidence that hot DBs contain traces of carbon which can be used to determine the temperatures of these objects. We present the results of our investigation of GD 190.

Radial Distance Dependence of the Solar Wind Speed at High Latitudes Observed by Interplanetary Scintillation
DOI: 10.1016/S0273-1177(99)00635-3 Bibcode: 2000AdSpR..25.1947Y

Tokumaru, M.; Kojima, M.; Yokobe, A.

We have investigated the radial distance dependence of the solar wind speed during the years 1995 and 1996 using interplanetary scintillation (IPS) observations at the Solar-Terrestrial Environment Laboratory. We derived solar wind velocity distributions for regions inside and outside of 0.3 AU separately using a computerized tomography method to …

Initial Results from the XUV Doppler Telescope
DOI: 10.1016/S0273-1177(99)00583-9 Bibcode: 2000AdSpR..25.1739K

Kano, R.; Kobayashi, K.; Tsuneta, S. +6 more

We developed a unique telescope to obtain simultaneous XUV images and the velocity maps by measuring the line-of-sight Doppler shifts of the Fe XIV 211A&ring line (T = 1.8 MK): the Solar XUV Doppler Telescope (hereafter XDT). The telescope was launched by the Institute of Space and Astronautical Science with the 22nd S520 rocket on January 31,…

Recognition of Space Weather Impact on the Isophot Detectors
DOI: 10.1023/A:1008069822196 Bibcode: 2000ExA....10..369C

Klaas, Ulrich; Castañeda, Hector O.

The effects of changes in the space environment on the ISOPHOT photoconductive detectors over the whole ISO mission were studied using the complete set of responsivity check measurements taken after the curing of the detectors. We found that the responsivity of the Ge-based, low bias voltage far-infrared detectors (P3, C100, and C200) is sensitive…

Kinematics of a Sample of Visual Double Stars
DOI: 10.2298/SAJ0062101O Bibcode: 2000SerAJ.162..101O

Olevic, D.; Cvetkovic, Z.; Dacic, M.

The Hipparcos-Input Catalogue also contains about 8000 already known visual double stars. In the framework of this-project campaign, in addition to other parameters, were also determined the parallaxes ?, as well as the polar coordinates ? and ? for double stars. On the basis of a comparison of these data to those obtained earlier from the ground …

Supernova Theory
DOI: 10.1016/S0920-5632(99)00887-7 Bibcode: 2000NuPhS..81..283L

Lattimer, J. M.

Supernova theory relies heavily upon the underlying equation of state (EOS). The role of the EOS during stellar collapse, and recent attempts to delineate the EOS from astrophysical observations, are discussed
